BB, perhaps the one piece base may not be more solid or secure than a two piece but it is certainly not less. I have both one and two piece leupold and weaver bases. It is my opinion that the one piece base in most cases is more solid due to the fact that one large solid piece of metal is definitely stronger than two small ones. While I don't have the experience and training you do, I've been shooting long enough to know what I like and what I don't.
